Five-and-twenty years ago, the 1500 scientists signed a letter warning for the mankind that it is necessary to change the ways to save the planet. A new letter, the marking of the anniversary of that first message, it has until now been signed by 15,000 scientists, and they say that the reason for the fee increase is that things have gotten much, much worse.
The last campaign, goes by the hashtag #ScientistsWarningToHumanity on Twitter was founded by William Ripple of Oregon State University’s College of Forestry, the CBC reports.
Ripple says he learned about the original 1992 warning last February and decided to update the worry he found there with new data. “The developments,” he says, “are alarming.” Ripple says he found a decrease in freshwater availability, reduces the biodiversity and climate change, among other things.
The only good news that he found a rapid decline in the depletion of the ozone layer. Ripple says that the last 25 years have seen a 62% increase in the carbon dioxide emissions and a 35% increase in the human population, causing a huge burden on the environment.
“We are a danger to our future by not reining in our intense, but geographically and demographically uneven material consumption,” the letter reads, “and by the non-perception of the continued rapid growth of population as a fundamental driver of many ecological and even societal threats.” Wrinkle and his team warn that if changes are not made, there will be irreversible loss of biodiversity and increase of natural disasters and human misery, the Independent reports.
